Recently, data-driven approaches in the field of material modeling have gained significant attention. A major advantage these is direct integration experimental results into models. Nevertheless, artificial neural networks (ANNs) are especially challenging to interpret from a physical point view, since internal processes ANNs difficult understand. In this work new automatic method for generatio...

In this research, the exponential stretched based hyperelastic strain energy was modified to provide the unstressed initial configuration. To this end, as the first step, the model was calibrated by the experimental data to find the best material parameters. The fitting results indicated material stability in large deformations and basic loading modes. In the second step, the initial pseudo str...

An elastomer is a polymer with the property of viscoelasticity, generally having notably low Young's modulus and high yield strain compared with other materials.  Elastomers, in particular rubbers, are used in a wide variety of products ranging from rubber hoses, isolation bearings, and shock absorbers to tires. Rubber has good properties and is thermal and electrical resistant. We used carbon ...

Coated functionally graded materials (FGMs) are used in several industrial structures such as turbine blades, cutting tools, and aircraft engines. Given the need for analytical numerical analysis of these complex structures, a mathematical model tricoated FG is presented first time this paper. The objective work was to analyze analytically buckling problem unidirectional (1D), bidirectional (2D...

Abstract In this work a number of selected, isotropic, invariant-based hyperelastic models are analyzed. The considered constitutive relations hyperelasticity include the model by Gent (G) and its extension, so-called generalized (GG), exponential-power law (Exp-PL) power (PL). material parameters under study have been identified for eight different experimental data sets. As it has demonstrate...
